The sohematio representation of the crystal structure of L1MPO4 compounds showing the HCP oxygen array with MO and PO4 groups.

The soiid-state structure of 2,6-2. Hydrogen atoms have been omitted for clarity

The soil considered as thin film stratified media.

The soil hydrogen permeation electrode mounted in a general probe used for screening soil corrosi v-ity.

The soil itself contained sufficient available energy material for a near-maximum rate of denitrification.

The soil mechanics triangle .

The soil P cycle.

The soil salts along the coast of Ross Island contain strontium and sulfur that originated from the volcanic rocks and from seawater. The isotopic compositions of strontium and sulfur in the soil salts are constrained by two isotopic mixing hyperbolas whose shapes depend on the assumed concentrations of strontium and sulfur expressed by the parameter K. The iso-

The solar flux spectrum in the 120-800 nm wavelength region at about 30 km altitude to show the atmospheric window in the 185-215 nm wavelength region.

The solar irradiance from X 1 nm to X 0.1 mm and normalized black-body radiation for T 5770 K. Solar irradiance data are from SOLAR2000 http

The solar irradiance in the main figure of the solar spectrum 3 see also Chapter 2.

The solar radiation spectrum and its absorption in the earth s atmosphere

The solar rechargeable redox flow battery based on Li2W04lLil couples from

The solar refinery as the conceptual contribution of chemistry by chemical energy conversion to the sustainable use of renewable energy. The upstream part and the downstream parts need not to be colocalized in a practical realization. CSP stands for concentrated solar power. Green boxes indicate solar fuel products blue boxes stand for intermediate platform chemicals. The red arrows indicate flows of solar hydrogen to a storage and transport system for large-scale applications. The blue arrows show the major application lines for chemical production of solar fuels. The scheme also indicates the role of fertilizers from ammonia required in sustained use of biomass for energetic applications.

The solar spectrum at standard conditions . The dashed curve is the continuous spectrum of an opaque object at 5750 K, closely similar to the solar spectrum measured outside the atmosphere. However, on this scale of resolution, several solar Fraunhofer lines can be seen above 15000 cm 1. The unit is W m2 per cm 1

The solar spectrum. AMO indicates that the graph refers to conditions outside the normal atmosphere. Note that the relation between the wavelength in micrometers and the energy in electron results is 1.3 eV pm. Thus, 0.2 urn 6eV and 2.0 pm

The solar spectrum. The dark vertical lines are the Fraunhofer lines. See color plate 18 for a full-color version of the spectnim. Images created by Dr. Donald Mickey, University of Hawaii Institute for Astronomy, from National Solar Observatory spectral data. NSOS Kitt Peak FTS data used here were produced by NSF NOAO.

The SOLBLEND.WKI spreadsheet sheet allows conversion of pound quantities of solvents in a formulation to a volume basis so as to enable calculation of the solubility parameters for the solvent blend. A total of six solvents can be called up from the table that contains 289 solvents. Source
